    That's the only change, nothing else in that line.

>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: Management Server
>    Affects Versions: 4.5.0, 4.6.0
>            Reporter: Koushik Das
>            Assignee: Koushik Das
>             Fix For: 4.7.0
>
>
> Global setting to control agent load balancing threshold "agent.load.threshold" has a
description as "What percentage of the agents can be held by one management server before
load balancing happens" .
> When the above setting is set to a value of 1, the behavior in logs is "Scheduling agent
rebalancing task as the average agent load 1.0 is more than the threshold 1.0"
> The ambiguity if re-balancing should happen or not can be fixed either in the description
or in the actual behavior.
